The march will be led by the Rev. Al Sharpton.
Thousands are set to march to protest the death of an unarmed black man who died after being placed in a chokehold by a white New York police officer.
The Saturday march in Staten Island is being led by the Rev. Al Sharpton's National Action Network.
It begins on the street where the 43-year-old Eric Garner was placed in the fatal hold last month and ends at the office of Staten Island District Attorney Daniel Donovan, who this week said he's sending the case to a grand jury.
Sharpton and his fellow activists are demanding that the NYPD officers involved face criminal charges.
He'll be joined by members of Garner's family and relatives of Michael Brown, the unarmed 18-year-old shot to death by police in Missouri earlier this month.
